Frozen Mallet need some love.

currently: 700hp 30 AD

89.3% gold efficient

suggestion 1 700hp 40 AD passive

100.913044% gold efficient

pushing it a bit. suggestion 2 700 70 passive 132.72% gold efficient

before calling my suggestion riduculously broken and unfair for other items:

121.96% gold efficient without its two passives. which mean it's much more higher! more base damage more gold efficiency and if you add it become ridiculously efficient

104.67% efficient without it's 2 passive which mean it's higher too! the more armor they stack the more efficient it become which can become ridiculous

and now ...

is 103.75% gold efficient, without its passive

Armor becomes 692.84% gold efficient, when Warmog's Heart is activated and you have not taken damage in the last 8 seconds.

can be 52.27% gold efficient up to 2XX% gold efficient depending on who you building it,yes almost 2 time more efficient with the passive.

is 103.24% gold efficient with passive scaling with the item bonus health. gold efficiency is further increased by 0.6% for every 100 Bonus Health obtained (excluding its own HP).

other:

is 80.7% gold efficient :( this item need some love 45 armor and 450 hp is quite low the passive early game dmg got nerf quite a bit , could buff the stats or make sunfire cap stronger late game by making the passive dealt max % of your health in damage.

is now 84% gold efficient "golf clap"
